RF Exposure Evaluation

1. RF Exposure evaluation for the applying LMA transmitter

The RF exposure energy from each antenna of ThinkPad X41 Tablet Series satisfies the limit of SAR

compliance according FCC CFR 47 section 2.1093, Portable devices.

The maximum SAR measurement result for model WM3B2915ABG performed with the ThinkPad X41

Tablet Series was 0.884W/Kg.

Please refer to the measurement result of the separate SAR test report.

The test was performed with the co-located Bluetooth device (FCC ID: ANO20040700HER) in active and

transmitting simultaneously.

Note: the function to stop Tx diversity in “Tablet” operation mode

When the host PC is used in the “

Tablet

” operation mode, one of the diversity antennas has a possibility to

contact to the human’s body.

The system has a control switch to change the rotation angle of LCD screen,

then controls to stop the transmission diversity of the antenna, which will contact to the human’s body.

This function is employed for model WM3B2915ABG in order to minimize the RF exposure energy to the

human’s body.
